Hello to all.

Thanks for reading this post and being able to help.

 

I would like to use a free library Modbus ( http://www.ni.com/example/29756/en/ ) (I do not know if there is another free library Modbus).

I can not find examples of this library.

Somebody can show me how to read variable Y25 from PLC in Labview with this library?? I am using RS232.

Or a link where I can find information?

 

Thanks a lot.
